-LRB- CNN -RRB- -- Black Friday bargain hunters , do you ever get the feeling that you 're being sucked in somewhere against your control , rapidly descending to a dark , cold place ?

It could be that feeling after you snatch the last Xbox away from a 9-year-old . Or it could be a black hole .

Shoppers may have Black Friday , but NASA scientists have something that 's arguably better : Black Hole Friday .

NASA spent the day tweeting facts about black holes , including a handful of Black Friday-themed jokes .

If humor is n't your thing , the agency also tweeted out a black hole-themed game .

The space agency sent out over a dozen tweets and retweets on black holes .

The `` 2-for-1 deal '' was a hit , garnering over 1,000 retweets .

NASA defines a black hole as `` a place in space where gravity pulls so much that even light can not get out , '' where `` the gravity is so strong because matter has been squeezed into a tiny space . ''

The space agency also posted some fun and less-known facts about black holes : For example , some scientists believe that the smallest black holes are the size of a single atom .
